  • 최근 기후변화 때문에 태풍, 호우 등 자연재해로 수방시설물의 피해규모가 커지고 있으며 이러한 피해는 단일 재해요인이 아닌 여러 재해요인이 복합적으로 작용하여 발생하고 있다. 그러므로 도시의 안전성과 방재기능을 확보하기 위해서는 복합위험요소를 고려한 재해위험도의 진단 기술 및 종합적인 재해경감대책 수립을 위한 연구가 필요한 실정이다. 복합위험요소를 고려한 재해위험도 및 재해경감대책을 수립하기 위해서는 도시재해를 유발하는 다양한 요인들이 도시재해에 미치는 영향과 재해요인 중에서 어떠한 재해요인이 도시재해에 더 큰 영향을 미치는지에 대한 검토가 필요하다. 이에 본 연구에서는 정보전달 이론 중의 하나인 엔트로피 방법을 이용하여 복합위험요소를 고려하여 도시지역에 대한 재해위험도를 나타내는 복합위험지수의 가중치를 산정하고자 하였다. 복합위험지수의 가중치는 지표별 속성정보를 추출하여 정규화 과정을 거친 후, 속성별 엔트로피를 산정하여 지표별로 산정된다. 엔트로피 방법에 따라 산정된 가중치는 다른 가중치 산정 방법에 따라 산정된 가중치와의 비교 분석을 통하여 타당성을 검토할 것이며, 이렇게 산정된 가중치를 복합위험지수 산정에 적용한다면, 보다 현실성 있는 도시재해 위험성 또는 취약성 지수로 활용될 수 있을 것으로 판단된다.

  • The aim of this research was to develop a climate change vulnerability index at the district level (Si, Gun, Gu) with respect to the health care sector in Korea. The climate change vulnerability index was esimated based on the four major causes of climate-related illnesses : vector, flood, heat waves, and air pollution/allergies. The vulnerability assessment framework consists of six layers, all of which are based on the IPCC vulnerability concepts (exposure, sensitivity, and adaptive capacity) and the pathway of direct and indirect impacts of climate change modulators on health. We collected proxy variables based on the conceptual framework of climate change vulnerability. Data were standardized using the min-max normalization method. We applied the analytic hierarchy process (AHP) weight and aggregated the variables using the non-compensatory multi-criteria approach. To verify the index, sensitivity analysis was conducted by using another aggregation method (geometric transformation method, which was applied to the index of multiple deprivation in the UK) and weight, calculated by the Budget Allocation method. The results showed that it would be possible to identify the vulnerable areas by applying the developed climate change vulnerability assessment index. The climate change vulnerability index could then be used as a valuable tool in setting climate change adaptation policies in the health care sector.

  • The vulnerability analysis of climate change driven disaster has been used as institutional framework for the urban policies of disaster prevention since 2012. However, some problems have occurred due to the structure of vulnerability analysis, such as overweighted variables and duplicated application of variables of similar meaning. The goal of this study is to examine the differences of results between the method of current guideline and the method of weight equalization. For this, we examines the current structural framework of the vulnerability analysis, and performs empirical analysis. As a result, the extent and magnitude of vulnerability showed different spatial patterns depending on the weighting methods. Standardized weighting method relatively represented wider vulnerable areas compared to the pre-existing method which follows the current instruction manual. To apply the results of vulnerability analysis to urban planning process for disaster prevention, this study suggests that the reliability of the results should be ensured by improving analytical framework and detailed review of the results.

  • In this research, customized management performance index for small and medium enterprises in solar energy area was developed. To acquire management performance index, first Delphi technique is applied and secondly, AHP(Analytic Hierarchy Process) used to give weight to each main index and then final management performance index was achieved. By developing management performance index, top management could manage their company more efficiently.

  • Groundwater management vulnerability was assessed using TOPSIS (Techniques for Order Performance by Similarity to Ideal Solution) for 21 administrative districts in Nakdong river basin. Ten indicators were selected for 21 administrative districts in the Nakdong river basin by collecting natural, human, and social data sets. The selected indicators were standardized using rescale method, and each indicator was weighted by considering the questionnaire of expert group. The results of the weights determination survey showed that the annual average groundwater level index was 0.157 and this is the highest value. The annual average precipitation index was 0.154 and the annual groundwater recharge index was 0.152. The lowest weighted index was 0.043 for population density. Finally, the result of assessment of groundwater management vulnerability showed that Sangju-si was the most vulnerable to groundwater management among 21 administrative districts in Nakdong river basin because the annual average precipitation, annual average groundwater recharge, and annual average groundwater use indicators were highly vulnerable. The second and the third vulnerable regions were Yecheon-gun and Haman-gun respectively. The assessment of groundwater management vulnerability for the five major river basins in Korea can be a essential basis for the establishment of groundwater management policy.

  • In this study, the evaluation index was developed to design the project evaluation model, and the weight was given through the AHP survey. project was evaluated for the first time by using the designed evaluation model for the field appraisal. As a result, it was revealed that the weight of the propriety index of the participant effect and the project content was the highest among 20 indexes. This study is significant in having built a base on which the evaluation system could be stabilized, by developing the integrative project evaluation model of . However, we have yet to adequately address the evaluator's acceptability and efficacy in evaluating indicators. The validity and continuity of the evaluation model will be secured through this.

  • 다층 퍼셉트론(MLP) 학습 이론인 오류 역전파 알고리즘은 델타룰과 최급 하강법을 사용하기 때문에 학습시 많은 시간이 소요된다는 단점을 가지고 있다. 때문에 신경망에서의 잘못된 초기 가중치 선택은 오류 역전파 알고리즘을 사용하는 신경망에서의 현격한 학습 성능저하를 발생시키게 된다. 본 논문에서는 학습시 오류 역전파 알고리즘의 수렴시간을 개선하기 위한 신경망의 동적 초기 가중치 선택 알고리즘을 제안한다. 이 알고리즘은 학습전 기존의 선택 가중치와 모든 가중치가 1.0 또는 -1.0 값을 가지는 가중치 집합에서 가중치 변동률을 선측정하여 이들 중 가장 변동률이 큰 경우를 초기 가중치 집합으로 선정하게 된다. 즉, 초기의 가중치 변동률을 차후 성능을 판단하는 지표로 사용하여 잘못된 가중치 선택으로 인한 최악의 학습효율의 가능성을 배제시키고 다층 신경망의 학습특성상 평균 이상의 학습효율을 보장하는 초기 가중치 선택방법이다.

  • Qualitative management structure of construction companies in Korea are relatively inadequate in comparison with quantitative growth. To improve qualitative management structure, we need to make impartial performance measurement system which arouse participants responds. It is important to select and decide performance measurement index to company and participants. And it is also important to take the weights. For that, we figure out the weights of performance measurement with HSC by Kaplan & Norton.'1'o find out the characteristics of the weights which was classified according to size of the construction company, we analyse and compare with each weights. The result of this Paper will contribute to operate performance measurement system that make raise efficiency and maximize the performance of companies.

  • The aim of this study is to compare and analyse the evaluation or performance indicators for academic libraries suggested at domestic and foreign. For the study, evaluation indicators of the various evaluation models(IFLA, ISO, ALA/ACRL, LA, HEFCE, CERLIM, JUAA, UNICOOP. KLA) was analysized. Evaluation or performance indicators should shed light on inputs and outputs of resource, levels of demand and satisfaction, the library effectiveness, and operating efficiency. There is a great deal of work going on at present, but as yet there is no greed set of indicators that can be across all academic libraries. Therefore, new evaluation indicators for physical and electronic libraries should be developed.
